Version dependencies are supposed to be noted in the rpms and this isn't gentoo - the apis aren't generally supposed to be changing at all or you couldn't expect your own and 3rd party applications to continue to run. > It is likely that many CentOS users think they aren't bothered by > these issues, but CentOS is used in a lot of production environments, > and I bet there will be some surprises. I've fairly routinely updated individual packages only across minor rev changes or held some back without problems. Your argument would be more convincing if you had several examples of update combinations not prevented by package dependencies that will break something. -- Les Mikesell lesmikesell at gmail.com
